MacBook gets stuck on white screen after yellowish apple logo screen?

Ok, i really need help!

When i try to turn on my macbook pro 15" late 2011 model on, it dos the chime like normal and apple logo appears but seems to have a yellowish highlight right on top the apple logo, not the whole screen. Just the logo is highlighted. After that it gets stuck at white screen.

• It doesn't boot in safe mode
• It doesn't boot in recovery mode
• I've reseted PRAM
• I've tried every Macbook shortcut.
• I uninstalled hard drive and it seems to be working fine, i was able to retrieve my important docs with an enclosure.
